S-norms and Anti fuzzy ideals of BCI-algebras

In this paper, as using S-norms, the concepts of anti fuzzy implicative ideals, anti fuzzy closed implicative ideals and anti fuzzy commutative ideals of BCI-algebras are introduced and presented some fundamental properties of them. Next the concepts of union and direct sum of them are investigated some basic properties related to them are established. Finally, homomorphisms of BCI-algebras are used about them and some algebraic properties of them are showed.
